I really like the px4 storm but I read and have been told that they can jam easily in dirty conditions. I was told that dirt can get into the rotating barrel and cause it to malfunction. I've read a lot of great reviews about this pistol but I don't want to buy something that is unreliable in certain conditions. So I'd like to hear from anyone who owns one or has owned one what you think of them. I either want to buy the .45acp or 9mm model.
